Manufacturing process of tube cap

Manufacturing process of tube cap  

Manufacturing pipe cap first to select material, pipe cap to choose the appropriate steel plate, with template marking with oxyacetylene flame cutting, clean up the iron oxide and gas cutting splashes and other residues on the plate, and the raw materials of the furnace, batch number and pipe specifications, project name, number clearly identified.  Cap pressing molding: put the blank into the heating furnace, heating up to the required temperature above 400℃ at a rate of 200℃/h or less, and heat it to the temperature required by the technology, and keep it warm.  Put the heated blank into the heated mold, and graphite powder should be evenly added on the surface of the mold to make the blank concentric in the axial direction of the mold.  Start the hydraulic system to ensure that the pressure is greater than 8MPa. Measure the billet temperature with an infrared thermometer when applying pressure.  In the process of pressing, and to the pressure balance.  Heat treatment: heat treatment of pipe caps in furnace according to heat treatment process.  Surface treatment: after heat treatment of the tube cap with sandblasting machine or polishing machine to remove the surface of the oxide.  Use of performance testing: according to the relevant standards, the mechanical properties of the pipe cap test, to ensure that the mechanical properties of the pipe cap meet the standards, testing items and sampling should meet the requirements of the relevant standards.  End processing, according to the design of the confirmed drawings for mechanical end machining groove.  The above is a simple introduction to the manufacturing process of the tube cap.
